Engine Fault light


Recommended Posts

Hi Keith, and welcome to the Club.


I am assuming that your S type is a 2.7 Diesel.  I am also assuming that the amber light comes on. Does your diagnostic check throw up a code, such as P0420?


If this is so, the most common issue is a sticky EGR valve.  This is something I have also had, and there are three cures.


1. Take off the valves, clean or replace.  Painstaking or expensive.

2. Use some Wynn's EGR cleaner which is stocked by Halfords. A bit less than £10.

3. Take the car out and give it a good blast with the "S" button on.  Very cheap and enjoyable!


Let me know how it goes.
